Member Function Documentation

capture()

teNackCode tcCameraLinkIO::capture ( tsCaptureRequest  asRequest )

virtual

Start a capture with this request. If the requests number of frames is tsNewRequest::CANCEL_CAPTURE then the current capture is stopped if possible.

Parameters

asRequest

- the request for capture being made.

Returns

a nack code if the capture parameters are inelligable for this IOChannel.

Implements tcIOChannel.

Reimplemented in SocCamera::tcBufferedCameraLinkIO.

enableStreaming()

void tcCameraLinkIO::enableStreaming

(

bool

abEnable

)

Enable/disable the reset bit to enable streaming.

Parameters

abEnable

- true to DISABLE the reset bit; false to enable it.

getOutputMode()

tcCameraLinkIO::teOutputMode tcCameraLinkIO::getOutputMode

(

)

getPixelClock()

double tcCameraLinkIO::getPixelClock

(

)

Get the configured pixel clock frequency.

Returns

the pixel clock frequency in MHz.

numTransferred()

uint32 tcCameraLinkIO::numTransferred ( )

protected

Reads the number of frames transferred out the camera link; this is an FPGA register.

Returns

the number of frames output since the last reset.

resetCamLink()

void tcCameraLinkIO::resetCamLink ( bool  abSet )

protected

Reset or un-reset the CameraLink component.

Parameters

abSet

- true to place the component in reset; false to take it out.

sendUpdate()

void tcCameraLinkIO::sendUpdate ( tsNewFrameMsg *  apMsg )

virtual

Process the update

Parameters

apMsg

- the update message.

Implements tcIOChannel.

Reimplemented in SocCamera::tcBufferedCameraLinkIO.

setBackpressureRows()

int tcCameraLinkIO::setBackpressureRows

(

int

rows

)

Set the number of rows to buffer before applying backpressure

Parameters

rows	number of rows, to apply 0-14, 15 = no backpressure

Returns

non-zero on error

setBpp()

teNackCode tcCameraLinkIO::setBpp ( SocCamera::teBPPMode  aeBppMode )

virtual

Sets the bits-per-pixel output of the camera.

Parameters

aeBppMode

- the bits per pixel mode.

Returns

the nack code for the operation

Implements tcIOChannel.

Reimplemented in SocCamera::tcBufferedCameraLinkIO.

setOutputMode()

teNackCode tcCameraLinkIO::setOutputMode ( tcCameraLinkIO::teOutputMode  aeOutputMode )

virtual

Toggles between the various camera link output modes (expanded, full, medium, base).

Parameters

aeOutputMode

- the mode to move into.

Returns

a nack code if the output mode is not supported.

Reimplemented in SocCamera::tcBufferedCameraLinkIO.

setPixelClock()

teNackCode tcCameraLinkIO::setPixelClock

(

double

anFreqMHz

)

Reconfigure the output clock to the specified frequency (closest fastest).

Parameters

anFreqMHz

- the desired frequency to set.

Returns

the nack code for the operation.

setPseudoSinglePort()

void tcCameraLinkIO::setPseudoSinglePort

(

bool

abEnable

)

Enable/Disable the pseudo-single port mode feature for a CIS2521 camera link output.

Parameters

abEnable

- true to enable the mode; false to disable it.

setSerDebug()

void tcCameraLinkIO::setSerDebug

(

bool

abOn

)

setTestPattern()

void tcCameraLinkIO::setTestPattern

(

bool

abEnable

)

Set the enable for the test pattern bit.

Parameters

abEnable

- true to enable test pattern, false to disable.
